Legal claims defining the scope of protection, as filed with the USPTO.

1

1. An electro-optical device comprising: a substrate; an organic electroluminescence (EL) element that is disposed on the substrate; a sealing part that is formed to cover the organic EL element; a color filter that includes a coloring layer formed on the sealing part; and an evaluation pattern that is measured to evaluate the color filter, the evaluation pattern being disposed on the sealing part.

2

2. The electro-optical device according to claim 1 , wherein the sealing part is formed over a first area on which the organic EL element is disposed and a second area surrounding the first area, the color filter is disposed on the sealing part in the first area, and the evaluation pattern is disposed on the sealing part in the second area.

3

3. The electro-optical device according to claim 1 , wherein the evaluation pattern includes a dimension evaluation pattern for evaluating dimensional accuracy of the coloring layer.

4

4. The electro-optical device according to claim 2 , wherein a height of the sealing part from the substrate in the first area is approximately equal to a height of the sealing part from the substrate in the second area.

5

5. The electro-optical device according to claim 2 , wherein the evaluation pattern is disposed near the first area in the second area.

6

6. The electro-optical device according to claim 1 , wherein the evaluation pattern includes a position evaluation pattern for evaluating position accuracy of the coloring layer.

7

7. The electro-optical device according to claim 2 , wherein the position evaluation pattern is disposed at a corner portion of an outer periphery in the second area.

8

8. The electro-optical device according to claim 1 , wherein the evaluation pattern includes the coloring layers of at least two colors, the color filter includes the coloring layers of at least two colors, the coloring layers of at least two colors are formed to partially overlap each other, and the coloring layers of at least two colors of the evaluation pattern are formed to be apart from each other.

9

9. The electro-optical device according to claim 8 , wherein the evaluation pattern includes a plurality of patterns for each of the coloring layers.

10

10. The electro-optical device according to claim 9 , wherein one pattern among the plurality of patterns is different from the other patterns.

11

11. The electro-optical device according to claim 1 , further comprising: a casing unit that has light shielding properties; wherein the evaluation pattern is covered with the casing unit.

12

12. An electronic apparatus comprising: the electro-optical device according to claim 1 .

13

13. An electronic apparatus comprising: the electro-optical device according to claim 2 .

14

14. An electronic apparatus comprising: the electro-optical device according to claim 3 .

15

15. An electronic apparatus comprising: the electro-optical device according to claim 4 .

16

16. An electronic apparatus comprising: the electro-optical device according to claim 5 .

17

17. An electronic apparatus comprising: the electro-optical device according to claim 6 .

18

18. An electronic apparatus comprising: the electro-optical device according to claim 7 .

19

19. An electronic apparatus comprising: the electro-optical device according to claim 8 .

20

20. An electronic apparatus comprising: the electro-optical device according to claim 9 .
